What does if matter if its a trailer or just an announcement? We know what Metroid looks like. We know as much about Prime 4 as we know about Beyond Good & Evil 2. And in both cases, we'll have to wait a few more years to play them.

I don't have a single one. 
Mario Odyssey
Shadow of the Collosus
Xenoblade 2

and Metroid Samus Returns (because it means the Metroid series isn't dead, and the Metroid series is the best video game series of all time, until Other M and Federation Force.) 

Dragon Ball Fighter Z. That shit was lit.

If I absolutely must choose one.... it's The Last Night.

Don't really have a single favorite one.

- Spiderman
- The Last Night
- Mario Odyssey
- Shadow of the Colossus Remake

Far Cry 5. It really looks like it will be a blast to play.

Ori and the Will of the Wisps by far. That trailer made me cry.
Mario Odyssey takes second place, looks really nice with the hat mechanic.
Also Mario+Rabbids looks great!

between Spiderman and mario odyssey

Spider-Man and God of War were my highlights at E3. Very hard to choose one between both, but I think am going with Spider-Man because it was more surprising with the first ever footage of the game.

Mario and Rabbids!
I can't believe how excited that game makes me.
